Here's a site I've encountered. Note that the "Welcome" string is truncated. My screen isn't narrow at all: it's more than 1000px wide. Screenshot

The Chrome browser's inspect tool says that the "Welcome" string isn't truncated at all. It's in a <span>:


To test the potentially truncated strings like this, I cannot just query the DOM. What are the tools and libraries available in the software testing industry to catch such undesirable modifications by the front end library?

In Python:

assert element.value_of_css_property("text-overflow") != "ellipsis"

in Java:



  • Thanks. I've confirmed that the css property "text-overflow" is applicable in my case. Apr 1, 2019 at 20:37
